The 53-6.7 antibody reacts with the 32-34 kDa alpha subunit of mouse CD8, known as CD8a or CD8 alpha. CD8a can form a homodimer (CD8 alpha-alpha), but is more commonly expressed as a heterodimer with a second chain known as CD8b or CD8 beta. CD8 acts as a co-receptor in antigen recognition and subsequent T cell activation that is initiated upon binding of the T cell receptor (TCR) to antigen-bearing MHC Class I molecules. The cytoplasmic domains of CD8 provide binding sites for the tyrosine kinase lck, facilitating intracellular signaling events that lead to T cell activation, development, and cytotoxic effector functions. CD8+ cytotoxic T cells (CTLs) play an important role in inducing cell death of tumor cells, as well as cells infected by virus, bacteria or parasites.
The 53-6.7 antibody is widely used as a phenotypic marker for mouse CD8a expression on cytotoxic T cells, thymocytes, as well as on certain cell types that do not also express the TCR, including some NK cells and lymphoid dendritic cells.

第二个问题：兔子不能免疫兔子的。免疫的一个重要概念是识别“自己”和“非己”，如果对自己的蛋白产生免疫反应，那就麻烦了。
可以类比器官移植，亲缘关系越近，越不容易产生免疫排斥。
你看这个抗体的质量怎么样，说明里面有没有说可以做组化，还是只能做western blot。
sc-153是兔抗大鼠ERK2的多克隆抗体
还有很多关于ERK1和ERK2的抗体
若想知道更多信息，你可以拨打Santa cruz 上海分公司的电话咨询

我们会按照你的实验需求推荐最适合你的产品。
想买消炎药怎么办?
去药店买药想买不是抗生素的消炎药，那工作人员说不是抗生素怎么消炎呢，请问知情网友求一替代品，谢了。
以下来自摆渡百科
细胞在发生凋亡时，会激活一些DNA内切酶，这些内切酶会切断核小体间的基因组DNA。细胞凋亡时抽提DNA进行电泳检测，可以发现180-200bp的DNA ladder。基因组DNA断裂时，暴露的3’-OH可以在末端脱氧核苷酸转移酶(Terminal
Deoxynucleotidyl Transferase, TdT) 的催化下加上荧光素 (FITC) 标记的dUTP
(fluorescein-dUTP) ，从而可以通过荧光显微镜或流式细胞仪进行检测，这就是TUNEL (TdT-mediated dUTP
Nick-End Labeling) 法检测细胞凋亡的原理。
